I am trying to narrow down why my throttle is closing. So we have 3 torque PIDS that seem to be important. We have Peak engine trq, predicted engine trq, and engine trq.
I have my peak engine trq tables set so that is always the highest value.
So when adjusting your VTT, I assume you need your predicted trq higher than your engine trq also, correct?
In the screen shot attached, with steady pedal position, my TB is closing from 100 to 50%, killing my boost. I notice in the logs that my predicted trq is way lower than my engine trq. I assume this is the cause of the TB closing. the throttle control source PID stays at torque for the pull.
To fix that, I need to go into the VTT tables and bump them in the areas I am being limited at, correct?
What are the current thoughts on dialing in the VTTs?
Thanks!
